Design and Implementation of Embedded System for Remote Upgrade of Concentrator G3-PLC & LoRa Master-Slave Module
In order to save a lot of human and material costs consumed in the process of upgrading the master and slave modules of the concentrator,especially to solve the failure and upgrading problems of the slave modules in hazardous areas and under bad weather,we propose a full-process automation design scheme for remote upgrade of embedded systems for the commonly used G3-PLC power carrier communication module and the LoRa wireless digital transmission module of the concentrator,and the whole process contains the transmission of the upgrading mirror file,the storage of the upgrading mirror file and the execution of the upgrading mirror file,at the same time,for the transmission part of downstream communication module,it simplifies the design of state machine and communication protocol framing for the methods and attributes of the upgrade standard of DLMS protocol.Eventually,the engineering experiment results show that using the master station or USB concentrator menu to trigger the batch remote upgrade of slave modules is remarkable,which proves the feasibility of the scheme and its engineering application value.
